DESCRIPTIO

Guaranteed

Reset Assertion at V

= 1V

8-Pin SO Plastic Package

2.0mA Maximum Supply Current

4.62V/4.37V Precision Voltage Monitor

Power OK/Reset Time Delay: 600ms

Minimum External Component Count

Superior Upgrade for DS1232

The LTC

1232 provides power supply monitoring,

watchdog timing and external reset for microprocessor

systems. A precise internal voltage reference and

comparator circuit monitor the power supply line. When

an out-of-tolerance condition occurs, the reset outputs

are forced to active states. The RST output is guaranteed

to remain logic low even with V

as low as 1V.

The LTC1232 has an internal watchdog timer which forces

the reset outputs to active states when the Strobe input is

not forced low prior to a preset time-out period. The

watchdog timing can be set to operate on time-out periods

of typically 150ms, 600ms or 1.2 seconds.

The LTC1232 performs push-button reset control.

The LTC1232 debounces the push-button input

and guarantees an active reset pulse width of 250ms

minimum.
